Food Manufacturing Africa is a journal that provides the latest news and trends about the manufacturing and processing of food and beverages — from raw material sourcing to manufacturing and packaging, right down to the distribution and marketing of finished goods — across the African continent. In its January 2019 issue, the online journal published our article addressing product recalls, brand erosion and risk mitigation of foreign object contamination when it comes to food processing and quality assurance.
The article, “What you should know about product testing,” discussed why product testing is necessary, outlined a comprehensive testing process, and described multi-frequency, multiscan contaminant detection technology.
Five key takeaways from the article include:
- A product test is the best way to discover what your existing inspection and detection technology may be missing.
- The more rigorous the product test, the better.
- Be aware that results could be influenced by factors like product presentation, package size, orientation, temperature, pitch, conveyor speed, frequencies, setup parameters and the placement of metal.
- Detailed reports should be generated for a thorough review of the results.
- Multi-frequency, multiscan technology can alleviate some sensitivity concerns and produce the highest probability of detection.
Metal detectors that are equipped with Multiscan technology enable operators to pick a set of up to five frequencies from 50 kHz to 1000 kHz. The technology then scans through each frequency at a very rapid rate. Running five frequencies at a time helps make the machine’s detection capability close to ideal for any type of metal you might encounter. Sensitivity is optimized, as you can choose to run the optimal frequency for each type of metal of concern. The result exponentially increases the probability of detection and reduces escapes.
